I wasn't referring to sender verification callbacks (which we do not use).
I was referring to recipient verification callforwards, where the edge MTA
doesn't know valid recipients but some internal (or even customer) MTA does.
Exim can configure these easily (but that doesn't help because Mailman
doesn't act like an MTA).  I don't know about any other MTAs in this regard.
